(I want to post this for the archives. It's an answer to a question
someone may someday search for.)
I just programmed an awt Frame which resizes itself to conform to a
certain aspect ratio. It is a media popup window which displays either
an image or a movie. I wanted a frame which would constrain it's
dimensions to the original ratio.
I tried a number of approaches and the one that finally worked for me
was by setting a component listener on the frame, listening for resize
events; I would then reset the size to conform to the aspect ratio. The
problem is that this didn't work -- the window would zoom back to the
drag-position size (*almost* always). I discovered thru experimentation
that sleeping the thread caused MY resize to take priority over (what I
assume to be) OSX's resize. Twenty milliseconds does it for me (ten
*ususally* works) but that is probably variable.
If there is a prescribed way to do this, I'd be keen to know.
peace

mediaPopup.addComponentListener( new ComponentAdapter()
{
private int RESIZE_SLEEP_DELAY = 10;
private float aspect = 1.0f;
private boolean isInitialized = false;
public void componentResized( final ComponentEvent
e ) {
if( ! isInitialized ) {
Dimension d = mediaPopup.getSize();
aspect = ((float)d.width) /
((float)d.height);
isInitialized = true;
}
